If the option StrictHostKeyChecking=no
is passed to OpenSSH ssh client and no key exists on the known_hosts
file for the target host, it will accept as good (and remembered for future connections) the first one received from the remote host.

$ssh = Net::OpenSSH->new($host,
user => $user, password => $password,
master_opts => [-o => 'StrictHostKeyChecking=
Note that disabling strict host key checking has some security implications that you should be aware of.
